$$e^{\frac{2 \sin{\left(x \right)}}{4}}$$

E^((2*sin(x))/4)

Detail solution

Let $u = \frac{2 \sin{\left(x \right)}}{4}$ .
The derivative of $e^{u}$ is itself.
Then, apply the chain rule. Multiply by $\frac{d}{d x} \frac{2 \sin{\left(x \right)}}{4}$ :
1. The derivative of a constant times a function is the constant times the derivative of the function.
  1. The derivative of a constant times a function is the constant times the derivative of the function.
    1. The derivative of sine is cosine:
      
      $\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}$
    So, the result is: $2 \cos{\left(x \right)}$
  So, the result is: $\frac{\cos{\left(x \right)}}{2}$
The result of the chain rule is:

$\frac{e^{\frac{2 \sin{\left(x \right)}}{4}} \cos{\left(x \right)}}{2}$
Now simplify:

$\frac{e^{\frac{\sin{\left(x \right)}}{2}} \cos{\left(x \right)}}{2}$

The answer is:

$\frac{e^{\frac{\sin{\left(x \right)}}{2}} \cos{\left(x \right)}}{2}$
